Democrats are in serious danger of becoming a Presidency only party like Republicans were from 1968 to 1994. As you can see from the Clinton and Obama years, having the White House but not control of Congress is completely worthless. Republicans in Congress essentially strap strings on Democratic Presidents and control them like a puppet.
Democrats are in serious danger of being shut out at the Congressional and local level.
Obama needs no help. He can raise $50 million at the flick of a light switch. And if he's destined to win anyway, why does he need much help?
Congress is where the action is. Congress makes the laws and sets the agenda, while the President simply goes along for the ride. Reelecting Obama with a Republican Congress is pretty much worthless. Republicans are already getting everything they want with Obama in the White House.
The 2010 elections decimated the Democratic party, wiping them out of office from every level from Congressman all the way down to city councils. What happened was akin to the 1958 midterm elections, which wiped Republicans out at almost every level and left them a powerless minority for 36 years.
Forget about Obama and work on regaining ground at the Congressional and local level in 2012.
